英文语法：虚拟条件句的倒装

　　　虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。英文语法例句如：

　　　 Were they here now, they could help us.
=If they were here now, they could help us.
Had you come earlier, you would have met him
=If you had come earlier, you would have met him.　
Should it rain, the crops would be saved.
=Were it to rain, the crops would be saved.

　　留心英文语法的小细节：
在虚构语气的从句中，动词'be'的从前时态一律用"were"，不用was， 即在从句中be用were代替。
If I were you, I would go to look for him.
假如我是你，就会去找他。
If he were here, everything would be all right.
如果他在这儿，所有都会好的。 内容来自

　　典型英文语法例题
_____ to do the work, I should do it some other day.
A. If were I　　 B. I were　C. Were I　D. Was I
答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但要留神，在虚构前提状语从句中，省略连词的倒装形式的句首不能用动词的缩略情势。如咱们可说 Were I not to do., 而不能说 Weren't I to do.
